`Application led J' 11.15r 28, 1915. Serial No. 42,329.

To all whom t may concern:

Be it known that I, Josnrn F. GEARY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new anduseful Improvement in Gage Devices, of which the In the type of presses to which invention more particularly applies, the space between the inner edge oi" the platen and the path traveled by the inking rollers is com paratively narrow and any gage device employed must be of such construction that it will not project into the path of the inking rollers. It is desirable, however, that the portion of the gage device against which the work is fed and for which it forms a stop, have relatively great adjustment for different sized work and for positioning the work at different places on the platen, and it is to provide a form of gage device which projects into the space between the inking rollers and the platen vand affords the desired relatively great adjustment of the stop devices for the work, that I have devised my invention.

A further object is to provide a simple and inexpensive form of gage which may be readily applied to position on the platen and by which exceedingly line adjustments of the stop members for the work carried thereby may be effected.

Referring to the accompanying drawing, Figure 1 isk a plan view of a platen of a press showing a air of my improved gage devices positione thereon with a 'sheet of paper held in position by the gage devices; Fig. 2 is an enlarged broken section, taken at the line 2 on Fig. 1 and viewed in the direction of the arrow; Fig. 3 is a section taken at the line 3 on Fig.` 2 and viewed in the direction of the arrow; Fig. 4 is a perspective view of the outer end of the threaded innerrod of the device and the disconnectible foot, coperating therewith and acting as a stop for the paper; `and Fig. 5 another form oit' foot which may be used and which is desirable especially where the work to be printed is envelops.

An ordinary form of platen or" a printing press is represented at 6, the platen having pivoted thereto, as indicated at 7 and 8 at its opposite ends, bails 9 and 10 respectively which serve to clamp to the platen, the cushioning pad 11, usually paper.

My improved gage device in its preferred embodiment comprises a bearing member 12 containing anl internally threaded opening 13, this bearing member by preference being provided with a relatively thin section 14 adapted to be inserted between the bail 10V and the covering 11, as represented, to hold it in firm position, the bearing member 12 resting upon the upper side of the bail 10. The device also comprises a sleeve member or tube 15, externally threaded as represented at 16 to correspond with the threads 13 with which it engages adapting it to move endwise through the bearing member 12 when the member 15 is rotated as by turning it at the knurled section 17. The forward end of the member 15 is internally threaded as represented at 18, this thread being preferably of the same pitch as the thread 15 but extending in the opposite direction. In other words, one of the threads 15 and 18 is a right-hand thread and the other thereofis a left-hand thread. A rod 19 having screw threads 2() of the same pitch and extending in the same direction as the threads 18 telescopes with the member 15 and engages at its threads 20 with the threads 18, the rod 19 being provided at its outer end with the foot 21 against which the work to be printed is positioned and for which it Jforms a stop.

In the particular illustrated embodiment of my invention the forward end of the rod 19 is of reduced diameter as indicated at 22,

its extremity being square as indicated at 23, and the Jroot member 21 is formed with a rearwardly projecting tube section 24 adapted to lit over the outer end of the rod 19 and engage at a squared section 25 thereof with the shouldered end 23 of the rod when the foot is positioned on the rod as shown in Fig. 2. The foot 21 of Fig. 4 is preferably formed of two sections, the tubular section 24 and a plate section 26 forming the foot proper which is provided along its lower edge with projections 27 at which the foot foregoing .that by rotating the member 15 in thebearing member 12, it will move in or out of the latter depending upon the direction in which it is rotated, and by reason of thefact that the threaded rod 19 is held, by means of the foot 21, against turning, this rod will be caused to move lengthwise in the same direction that the member 15 moves, but at twice the speed, inasmuch as the inner and outer threads on the member` 15 are of the same pitch." lt will be understood, however, that if desired these threads ay be of different pitch.

The feature just described is of great benelit and advantage in a device of this character inasmuch as a relatively great range of adjustment may be provided to the foot member 21 with the minimum longitudinal movement of the member 15, which in moving lengthwise moves through the space between the rear edge of the platen and the i path of the inking rollers which space of necessity is of limited width.

' it will be manifest that va verv minute and f of the would be free to' rotate in the Furthermore,

delicate'adjustment of the gage device may be effected.

The-footy member 21 ispreferably constructed as describedin order that, if desired, the rod 19 may be released therefrom to vpermit it to turn with the member 15'when the latter is rotated and thus effect adjustment of the gagedevice through the medium single thread 15 instead of the double thread as hereinbefore'stated, it being desirable under some conditions of use that the adjustment which may be effected by the single thread 15, be utilized. i To so adjust would slip the' foot member 21 away from the rod 19 to disengage its squared section 23 from the square portion 25 of the foot, whereupon the rod 19 foot 21.

In the drawing my improved gage device is shown in the position in which it is placed when forming a stop for the lower edge of sheets of paper applied to the press, in which case it is preferred that at least two of the gage devices be employed as shown, the

paper being fed against the faces of the feet 21, as shown in Figs. 1 and 2.

The construction illustrated in Fig. 5 is the same as that shownin" Fig. a excepting tha-t the flange 28 carries a tongue 29 which is a desirable adjunct to the foot 21, espervcially where the objects'to be printed and fed against the gage devices, foot, however, form.

If desired, instead of providing threaded are envelops. The may be of any other suitable connections between the various relatively movable members, provision for adjustment may be otherwise made, as, for example, the threads may be omitted and clamping lneans, set screws or the like employed to maintain the adjustment. lThus, for example, the adjustable members which are connected with the bearing member may be adjustable relative to each other and to the bearing member by a sliding longitudinal movement, employing clamping means, set screws, or the like, for maintaining the adjustment.

lVhile l have illustrated and described certain embodiments of my invention, I do not wish to be understood as intending to limit it thereto, as the same may bc variously modified and altered without departing from the spirit of my invention.

l claim as new and desire to secure by Letters Patent:
